A little over a year ago, Google was activating 100,000 Android devices every day. That seemed like a huge number at the time, but compared what the future would bring, that's small-time. Several months later - in December, 2010 - that number had risen to 300,000 activation per day, effectively tripling the number of Android devices in just seven months. At Google I/O last month, it was announced that activations were still on the rise, and had hit 400,000 per month. Today, Andy Rubin took to Twitter to let us know how much Android has grown in just one month.

Five-Hundred-Thousand.

That's how many Android devices Google are activating every day as of now - a gain of 100,000 in just one month. That's really not even the most staggering news, either - Rubin also said that this number is growing by 4.4% every week, which is nearly 100,000 each month. This mean that by the end of July, Google should be activating almost 600,000 devices every-single-day. At that rate, by the end of 2011, more than 1 million Android devices will be activated on a daily basis.
